Later chapters in the book describe how the method creates the time the data architect will need to stay ahead of his team’s coders.

Although a relational database is still the primary database technology used, the data designer needs to be familiar with other technologies that may potentially be used, including columnar, massive parallel processing (MPP), NoSQL, online analytical processing (OLAP), and in-memory, in addition to BI appliances that may use a variety of these technologies along with specialized hardware and/or specific logical and physical data architectures. Volgorde. The required DI workflow and supporting DI code will likely require data movement, transformation, and integration with several databases.
